- Saturated fatty acids are so named because they are saturated with (a) hydrogen (b) water (c) hydroxyl groups (d) glycerol (e) double bondsUnlike saturated fatty acids, the tails of unsaturated fatty acids incorporate one or more _______. a. phosphate groups b. glycerols c. double bonds d. single bondsAccording to health experts, saturated fatty acids, whichcome from animal fats, are a major factor contributing tocoronary heart disease. What distinguishes a saturated fattyacid from an unsaturated fatty acid, and to what does theterm saturated refer? Recently, trans unsaturated fatty acids, or trans fats, which raise total cholesterol levels in the body,have also been implicated in heart disease. How does the cisstereoisomer differ from the trans configuration, and whateffect does the cis configuration have on the structure of thefatty acid chain?
- Lipoproteins transport dietary fats through the bloodstream and deliver them to the cells. Cholesterol (below) is mainly transported as a cholesterol ester via the condensation reaction of cholesterol and a free fatty acid.

- C) In biology, a very important concept is that evolution has produced organisms whose structures best perform their required function in the organism. Amazingly, this holds true for ll the levels of organization of matter from whole body parts right down to the molecules that they are made of. The function of glycogen in the body is long-term energy storage. Explain in detail how the chemical structure of glycogen corresponds to this function. aymere te heresuls of le-rancois cthesis that bre chansed.

In relatively mild conditions (180ºC and pressures of about 1.33 atm) a sufficient number of double bonds are hydrogenated and solidify liquid oils. This solid material, margarine, has a consistency similar to butter. Come up with a practical reason why oils don'tthey are completely hydrogenated during commercial hydrogenation processes.Most vitamins can be classified either as fat soluble, which resultsin their tendency to accumulate in the body (so that taking toomuch can be harmful), or water soluble, which results in theirtendency to be quickly eliminated from the body in urine. Examinethe structural formulas and space-filling models of these vitaminsand determine whether each one is fat soluble (mostly nonpolar) orwater soluble (mostly polar).
